Default Using a mini fridge to chill water

I saw this aution on ebay: http://cgi.ebay.com/ws/eBayISAPI.dll...category=16035 and thought why not put my resivor and rad inside a min fridge? For 30 bucks who wouldn't? The thing I'm guessing uses low wattage pelts. I could just drill to half inch holes into it, and presto! it would chill my coolant (Prestone and distilled water) I want to try to get my 2.4B SL6RZ to 3.8-3.9GHz (It's running at 3.6 now) BTW please take a look at my rig (my first oc'ed) and tell me if you like: www.geocities.com/aaronparsekian/rig01.jpg BTW all you kids out there don't mess with prestone antireeze it tastes horrible.

The only problem I think would be condensation problems around the waterblock and the possibility of frozen coolant. I read a story a while ago where the person used straight rubbing alcohol for his coolant.

Also, those minifridges wont arent made to cool something that is continuously putting out heat. Those are for pretty much keeping something cool. By putting a huge load on something like that, you run the high possibility of failure. If you wanted to do something like that, I would say get something much much beefier.

The link to your rig doesn't work. Antifreeze is sweet at first but leaves you with a hollow feeling inside.

damn link never works ;-( try my image gallery when they verify the pic. Prestone works mad nice! i guess there all the same glycol based green stuff, but I still get better results than swiftech. That stuff gives you a headache for days! lololol my rig gives me a hangover when I bleed it let me try to add a pic:

found something better: http://www.lowes.com/lkn?action=prod...7-46-EL02PPXMQ this fridge is not thermoelectric and it is almost exacly the same size as the shelf thing my rig is on now!

You can submerge your radiator in coolant/water. I was thinking of doing the same thing. Actually putting a large 20 gal reservoir in the basement, and put the radiator/heater core in it. Only trick is to remove the heat from the water in the reservoir.

Ahhhh yes,
the old mini-fridge under the table routine...
saw an article where this guy put 20 turns of 1/2'' copper thin wall tubing in a mini-fridge instead of a radiator/fan set up.
It looked trick. I'm not sure of the temps he got, but if they were outstanding I prolly would have rig something like that and tried to improve it...might be worth a try, now that the ambient is hell like.
Slider, did you see where the guy made a fountain over his cooling lines in a large reservior, kinda like a swamp cooler. As the water from the fountain evaporated the phase-change created coldness to the cooling tubes on his system. Large system, but if you got a basment?...

Yeah, I saw that. In the winter time, I won't need anything, since it's very cold down there. I have to put electric wire wraps on pipes to prevent freezing, because nothing sucks more than a burst pipe.

Just to clear a few things up:

1. Antifreze/Glycol if mixed with water at a 1 part glycol to 3 parts water, wont freeze until 0 F, a 1 to 1 mixture will go down to about -36 F

2. It WILL condensate if humidity levels are high, the block will condensate faster and at lower humidity.

3. Glycol isn't cold at room temp, it has almost the same properties as water, except it boils at a higher temp and freezes at a lower temp.

Your best bet would probably be to submerse the radiator in water inside the refregerator. It doesnt have to be extremely cold, as long as the inside refregerator temp is lower than the system liquid temp it will cool off. Also Glycol takes a little longer to heat up and cool off than water, so using it would actually hinder cooling performance.

i want some way to cool my rad or res but i want to be able to still cart my system to LAN partys.. can this be done but you could still move the system around pretty easy?

Condensation, the process by which a vapor loses heat and changes into a liquid,will occur when the coolant or block or whatever is cooler than the surounding ambient. The exact teperature that this happens is the "dew point" the temperature at which the air cannot hold all the moisture in it and dew begins to form. I agree that glycol based products are less efficient in PC cooling systems, however they would have no bering on the point that condensation would occur, as that would be determined by the surrounding ambient and humidity.
Also radiators are designed to rid the buildup of heat by moving air through them and not water. Coolers that are designed to give off the buildup of heat into water are totally different. They are attached to just about every fishing vessel in the fleet up here, "keel coolers" and they are a system of tubes that are bare with no fins that would interupt the smooth flow of ocean water around them, make them cavitate...word

Rewind,
I am doing research on that exact item. I am trying to design a selfcontained cooling system that is LAN friendly, cost effective and movable upon upgrading theCPU. If I am sucessful, I will sell you and 1000's like you one. But in answer to your question, everything out there has it's pros and cons. I do know this, that efficient H20 cooling requires s p a c e.

So submerging my rad in water is a bad idea? even if fins are in the way I'm sure I would see better results than air. I was also thinking of getting a metal container, attaching the cold side of a low wattage pelt to it, and running curled up 1/2" copper tubing through the cooled water. right now my 2.4B running at 3.6GHz is at 50*C ;-( I need to think of something quick. Thanks for all of the comments

i understand that H20 cooling you need space but the idea of drilling holes threw my mom and dads floors so i can get tubes to my 20 gallon res is just kinda scary maybe i will try a permint thing like that IF/when i get my lappy but for now its me and the koolance

i wonder how big thoes fridges are once you have all the cooling elemetns out and if they could mount on with out adding 7,000,000lbs haha

for 1k of hard earned, you can get the new Prometeia ll from Chip-con (-40 potential)
no holes in floor nessasary, just the case floor.

AntiM: 77kelvin?! now we're gettin somwhere. That's the smallest unit and it's the size of a full tower, However one could offset the cost by doing home liquification of O2. Is there a market for home brewed liquid oxygen? chilly find bro...

vapochill now sells their units standalone without cases so just buy that or a TEC. or dont buy a mini fridge that uses a TEC build a chiller with one.
